| In term of programming, a negative register is a clone of that register who conteins the two’s complement of the absolute value of first.

"Negative register" is an uncommon phrase. Need more info.
Can you quote the entire sentence where you saw it?

| sometime we add register in a design as pipeline so there is much more latency which use negative register to compensate latency!

Hmmm, could be negative *time* registers.
When you pipeline part of your data path to improve clock speed, you normally need to add equal delay registers to the other parts of your data path to maintain equal latency. I suppose those extra delay registers could be called "negative time registers" because they output previous data. Similar to z, z-1, z-2, z-3 mathematical notation.
